FerMENTORS The Rare Barrel Culture

Availability: Core culture. Available with every homebrew culture presale release (3 times per year)

Source: A unique blend of ale yeast, Brett and lactic acid bacteria (LAB) curated by The Rare Barrel in Berkeley, CA, USA

The Rare Barrel is the creator of world-class beers Impossible Soul, Soliloquy, There Are Rules, Ensorcelled, and Home, Sour Home.

The main fermentation driver in this culture is a Belgian saison strain. Beginning stages of fermentation produce classic bubblegum clove phenols.

The unique Brett character will start expressing within the first six weeks. Eventually pushing big tropical fruit and pineapple Brett character more than typical barnyard. With additional aging the pineapple character will become even more pronounced.

This culture is a reliable acidifier depending on the level of IBUs, with low levels acidifying within weeks and levels as high as 30 IBUs taking three to six months.

The Rare Barrel Culture is ideal for a wide range of Belgian and farmhouse ale styles like grisettes, saisons and American wild ales. Visit the official recipe page for inspiration when using this culture.
